2. Handling CautionsThis chapter provides important information on how to handle the transmitter. Read this carefully before using the transmitter.

EJX Series transmitters are thoroughly tested at the factory before shipment. When taking delivery of an instrument, visually check them to make sure that no damage occurred during shipment.

Also check that all transmitter mounting hardware showninfigure2.1isincluded.Ifthetransmitteris ordered without the mounting bracket and the process connector, the transmitter mounting hardware will not be included. After checking the transmitter, carefully repack it in its box and keep it there until you are ready to install it.

Figure 2.2 Name Plate (EJX110A)

2.2 UnpackingKeep the transmitter in its original packaging to prevent it from being damaged during shipment. Do not unpack the transmitter until it reaches the installation site.

2.3 StorageThe following precautions must be observed when storing the instrument, especially for a long period.

(a) Select a storage area which meets the following conditions:• It is not exposed to rain or subject to water

seepage/leaks.• Vibration and shock are kept to a minimum.• It has an ambient temperature and relative

humidity within the following ranges.

Ambient temperature: –40* to 85°C without integral indicator –30* to 80°C with integral indicator

*–15°Cwhen/HEisspecified.Relative humidity: 0% to 100% R.H. Preferred temperature and humidity: approx. 25°C and 65% R.H.

(b) When storing the transmitter, repack it carefully in the packaging that it was originally shipped with.

(c) If the transmitter has been used, thoroughly cleanthechambersinsidethecoverflanges,sothatthereisnoprocessfluidremaininginside.Before placing it in storage, also make sure that the pressure-detector is securely connected to the transmitter section.


IM 01C25B01-01E

2.4 Selecting the Installation Location

The transmitter is designed to withstand severe environmental conditions. However, to ensure that it will provide years of stable and accurate performance, take the following precautions when selecting the installation location.

(a) Ambient TemperatureAvoid locations subject to wide temperature variationsorasignificanttemperaturegradient.If the location is exposed to radiant heat from plant equipment, provide adequate thermal insulation and/or ventilation.

(b) Ambient AtmosphereDo not install the transmitter in a corrosive atmosphere. If this cannot be avoided, there must be adequate ventilation as well as measures to prevent the leaking of rain water and the presence of standing water in the conduits.

(c) Shock and VibrationAlthough the transmitter is designed to be relatively resistant to shock and vibration, an installation site should be selected where this is kept to a minimum.

(d) Installation of Explosion-protected TransmittersAn explosion-protected transmitters is certifiedforinstallationinahazardousareacontainingspecificgastypes.Seesubsection2.9 “Installation of an Explosion-Protected Transmitters.”

2.5 Pressure Connection

WARNING

• Never loosen the process connector bolts when an instrument is installed in a process. The device is under pressure, and a loss of seal can result in a sudden and uncontrolled releaseofprocessfluid.

• Whendrainingtoxicprocessfluidsthathavecondensed inside the pressure detector, take appropriate steps to prevent the contact ofsuchfluidswiththeskinoreyesandtheinhalationofvaporsfromthesefluids.

The following precautions must be observed in order to safely operate the transmitter under pressure.

(a) Make sure that all the process connector bolts aretightenedfirmly.

(b) Make sure that there are no leaks in the impulse piping.

(c) Never apply a pressure higher than the specifiedmaximumworkingpressure.

2.6 WaterproofingofCableConduit Connections

Apply a non-hardening sealant to the threads to waterproof the transmitter cable conduit connections.(Seefigure6.8,6.9and6.10.)

2.7 Restrictions on Use of Radio Transceivers

IMPORTANTAlthough the transmitter has been designed to resist high frequency electrical noise, if a radio transceiver is used near the transmitter or its external wiring, the transmitter may be affected by high frequency noise pickup. To test this, start out from a distance of several meters and slowly approach the transmitter with the transceiver while observing the measurement loop for noise effects. Thereafter use the transceiver outside therangewherethenoiseeffectswerefirstobserved.

2.8 Insulation Resistance and Dielectric Strength Test

Since the transmitter has undergone insulation resistance and dielectric strength tests at the factory before shipment, normally these tests are not required. If the need arises to conduct these tests, heed the following:

(a) Do not perform such tests more frequently than is absolutely necessary. Even test voltages that do not cause visible damage to the insulation may degrade the insulation and reduce safety margins.


IM 01C25B01-01E

(b) Never apply a voltage exceeding 500 V DC (100 V DC with an internal lightning protector) for the insulation resistance test, nor a voltage exceeding 500 V AC (100 V AC with an internal lightning protector) for the dielectric strength test.

(c) Before conducting these tests, disconnect all signal lines from the transmitter terminals. The procedure for conducting these tests is as follows:

• Insulation Resistance Test

1) Short-circuit the + and – SUPPLY terminals in the terminal box.

2) Turn OFF the insulation tester. Then connect the insulation tester plus (+) lead wire to the shorted SUPPLY terminals and the minus (–) leadwire to the grounding terminal.

3) Turn ON the insulation tester power and measure the insulation resistance. The voltage shouldbeappliedasbrieflyaspossibletoverifythattheinsulationresistanceisatleast20MΩ.

4) After completing the test and being very careful not to touch exposed conductors disconnect the insulationtesterandconnecta100kΩresistorbetween the grounding terminal and the short-circuiting SUPPLY terminals. Leave this resistor connected at least one second to discharge any static potential. Do not touch the terminals while it is discharging.

• Dielectric Strength Test

1) Short-circuit the + and – SUPPLY terminals in the terminal box.

2) Turn OFF the dielectric strength tester. Then connect the tester between the shorted SUPPLY terminals and the grounding terminal. Be sure to connect the grounding lead of the dielectric strength tester to the ground terminal.

3) Set the current limit on the dielectric strength tester to 10 mA, then turn ON the power and gradually increase the test voltage from ‘0’ to thespecifiedvoltage.

4)Whenthespecifiedvoltageisreached,holditfor one minute.

5) After completing this test, slowly decrease the voltage to avoid any voltage surges.

2.9 Installation of an Explosion-Protected Instrument

CAUTION• Thetemperatureandpressureoffluidshould

be maintained at levels that are consistent with normal operating conditions.

• The ambient temperature should be maintained at a level that is consistent with normal operating conditions.

• Please take care to prevent water hammer and the like from inducing excessive pressures in pipes and valves. If phenomena are likely, install a safety valve or take some other appropriate measure to prevent pressure from exceeding PS.

• Take appropriate measures at the device or system level to protect transmitters if they are to be operated near an external heat source.

2.12 Low Voltage DirectiveApplicable standard: EN61010-1

(1) Pollution Degree 2

"Pollution degree" describes the degree to which a solid, liquid, or gas which deteriorates dielectric strength or surface resistivity is adhering. " 2 " applies to normal indoor atmosphere. Normally, only non-conductive pollution occurs. Occasionally, however, temporary conductivity caused by condensation must be expected.

(2) Installation Category I

"Overvoltage category (Installation category)" describesanumberwhichdefinesatransientovervoltage condition. It implies the regulation for impulse withstand voltage. " I " applies to electrical equipment which is supplied from the circuit when appropriate transient overvoltage control means (interfaces) are provided.

5. Installing Impulse Piping5.1 Impulse Piping Installation

PrecautionsThe impulse piping that connects the process outputs to the transmitter must convey the process pressure accurately. If, for example, gas collects inaliquid-filledimpulseline,orthedrainforagas-filledimpulselinebecomesplugged,itwillnot convey the pressure accurately. Since this will cause errors in the measurement output, select theproperpipingmethodfortheprocessfluid(gas, liquid, or steam). Pay careful attention to the following points when routing the impulse piping and connecting the impulse piping to a transmitter.

5.1.1 Connecting Impulse Piping to a Transmitter

(1) ChecktheHighandLowPressureConnections on the Transmitter (Figure 5.1)

Symbols “H” and “L” have been placed on the capsule assembly to indicate high and low pressure side. With differential pressure transmitters, connect the high pressure side impulse line to the “H” side, and the low pressure side impulse line to the “L” side.

With gauge/absolute pressure transmitters, connect the impulse line to the ‘H’ side.

(2) Changing the Process Connector Piping Connections (Figure 4.1) (for differential pressure transmitters)

The impulse piping connection distances can be changed between 51 mm, 54 mm and 57 mm by changing the orientation of the process connectors. This is convenient for aligning an impulse line with a process connectors.

(3) Tightening the Process Connector Mounting Bolts

After connecting an impulse line, tighten the process connector mounting bolts uniformly.

(4) Removing the Impulse Piping Connecting Port Dustproof Cap

The impulse piping connecting port on the transmitter is covered with a plastic cap to keep out dust. This cap must be removed before connecting the line. (Be careful not to damage the threads when removing this cap. Never insert a screwdriver or other tool between the cap and port threads to remove the cap.)

(5) Connecting the Transmitter and 3-Valve Manifold (for differential pressure transmitters)

A 3-valve manifold consists of two stop valves to block process pressure and an equalizing valve to equalize the pressures on the high and low pressure sides of the transmitter. Such a manifold makes it easier to disconnect the transmitter from the impulse piping, and is convenient when adjusting the transmitter zero point.

There are two 3-valve manifold types: the pipe-mounting type and the direct-mounting type; care should be taken with respect to the following points when connecting the manifold to the transmitter.


IM 01C25B01-01E

Pipe-Mounting Type 3-Valve Manifold (Figure 5.2)

1) Screw nipples into the connection ports on the transmitter side of the 3-valve manifold, and into the impulse piping connecting ports on the process connectors. (To maintain proper sealing, wind sealing tape around the nipple threads.)

2) Mount the 3-valve manifold on the 50 mm (2-inch) pipe by fastening a U-bolt to its mounting bracket. Tighten the U-bolt nuts only lightly at this time.

3) Install the pipe assemblies between the 3-valve manifold and the process connectors and lightly tighten the ball head lock nuts. (The ball-shaped ends of the pipes must be handled carefully, since they will not seal properly if the ball surface is scratched or otherwise damaged.)

4) Now tighten the nuts and bolts securely in the following sequence:

NOTEAfter completing the connection of the transmitter and 3-valve manifold, be sure to CLOSE the low pressure and high pressure stop valves, OPEN the equalizing valve, and leave the manifold with the equalizing valve OPEN. You must do this in order to avoid overloading the transmitter from either the high or the low pressure side when beginning operation. This instruction must also be followed as part of the startup procedure (chapter 7.)


IM 01C25B01-01E

5.1.2 Routing the Impulse Piping

(1) Process Pressure Tap Angles

If condensate, gas, sediment or other extraneous material in the process piping gets into the impulse piping, pressure measurement errors may result. To prevent such problems, the process pressure taps mustbeangledasshowninfigure5.4accordingtothekindoffluidbeingmeasured.

NOTE• Iftheprocessfluidisagas,thetapsmustbe

Figure 5.4 Process Pressure Tap Angle (For Horizontal Piping)

(2) Position of Process Pressure Taps and Transmitter

If condensate (or gas) accumulates in the impulse piping, it should be removed periodically by opening the drain (or vent) plugs. However, this will generate a transient disturbance in the pressure measurement, and therefore it is necessary to position the taps and route the impulse piping so that any extraneous liquid or gas generated in the leadlines returns naturally to the process piping.

• Iftheprocessfluidisagas,thenasarulethetransmitter must be located higher than the process pressure taps.

• Iftheprocessfluidisaliquidorsteam,thenasarule the transmitter must be located lower than the process pressure taps.

(3) Impulse Piping Slope

The impulse piping must be routed with only an upward or downward slope. Even for horizontal routing, the impulse piping should have a slope of at least 1/10 to prevent condensate (or gases) from accumulating in the pipes.

(4) Temperature Difference Between Impulse Lines (for differential pressure transmitters)

If there is a temperature difference between the high and low impulse lines, the density difference ofthefluidsinthetwolineswillcauseanerrorinthemeasurementpressure.Whenmeasuringflow,impulse lines must be routed together so that there is no temperature difference between them.

(5) Condensate Pots for Steam Flow Measurement (for differential pressure transmitters)

If the liquid in the impulse piping repeatedly condenses or vaporizes as a result of changes in the ambient or process temperature, this will causeadifferenceinthefluidheadbetweenthehigh pressure and low pressure sides. To prevent measurement errors due to these head differences, condensate pots are used when measuring steam flow.

(6) Preventing Wind Speed Effects in Very Low Differential Pressure Measurement (for differential pressure transmitters)

IMPORTANTWhen using a differential pressure transmitter to measure very low pressures (draft pressure), the low pressure connection port is left open to atmospheric pressure (the reference pressure). Any wind around the differential pressure transmitter will therefore cause errors in the measurement. To prevent this, it will be necessary either to enclose the transmitter in a box, or to connect an impulse line to the low pressure side and insert its end into a wind-excluding pot (cylindrical with a base plate).


IM 01C25B01-01E

(7) Preventing Freezing

Ifthereisanyriskthattheprocessfluidintheimpulse piping or transmitter could freeze, use a steam jacket or heater to maintain the temperature ofthefluid.

NOTEAfter completing the connections, close the valves on the process pressure taps (main valves), the valves at the transmitter (stop valves), and the impulse piping drain valves, so that condensate, sediment, dust and other extraneous material cannot enter the impulse piping.

5.2 Impulse Piping Connection Examples

Figure 5.5 and 5.6 show examples of typical impulse piping connections. Before connecting the transmitter to the process, study the transmitter installation location, the process piping layout, andthecharacteristicsoftheprocessfluid(corrosiveness,toxicity,flammability,etc.),inorderto make appropriate changes and additions to the connectionconfigurations.

Note the following points when referring to these piping examples.

• The high pressure connecting port on the transmitter is shown on the right (as viewed from the front).

• The transmitter impulse piping connection is shown for a vertical impulse piping connection configurationinwhichthedirectionofconnection is either upwards or downwards.

• If the impulse line is long, bracing or supports should be provided to prevent vibration.

• The impulse piping material used must be compatible with the process pressure, temperature, and other conditions.

• A variety of process pressure tap valves (main valves) are available according to the type ofconnection(flanged,screwed,welded),construction (globe, gate, or ball valve), temperature and pressure. Select the type of valve most appropriate for the application.

6. Wiring6.1 Wiring Precautions

IMPORTANT• Lay wiring as far as possible from electrical

noise sources such as large capacity transformers, motors, and power supplies.

• Remove the electrical connection dust cap before wiring.

• All threaded parts must be treated with waterproofingsealant.(Anon-hardeningsilicone group sealant is recommended.)

• To prevent noise pickup, do not pass signal and power cables through the same ducts.

• Explosion-protected instruments must bewiredinaccordancewithspecificrequirements (and, in certain countries, legal regulations) in order to preserve the effectiveness of their explosion-protected features.

• The terminal box cover is locked by an Allen head bolt (a shrouding bolt) on ATEX flameprooftypetransmitters.Whentheshrouding bolt is driven clockwise using an Allen wrench, it goes in. The cover lock can then be released and the cover can be opened by hand. See subsection 8.4 “Disassembly and Reassembly” for details.

• Plug and seal an unused conduit connection.

6.2 Selecting the Wiring Materials

(a) Use stranded leadwires or cables which are the same as or better than 600 V grade PVC insulated wire (JIS C3307) or its equivalent.

(b) Use shielded wires in areas that are susceptible to electrical noise.

(c) In areas with higher or lower ambient temperatures, use appropriate wires or cables.

(d) In environment where oils, solvents, corrosive gases or liquids may be present, use wires or cables that are resistant to such substances.

(e) It is recommended that crimp-on solderless terminal lugs (for 4 mm screws) with insulating sleeves be used for leadwire ends.

Zero point adjustment can be done by turning the transmitter’s zero-adjustment screw or by using the communicator. This section describes the procedure for the zero-adjustment screw. For the communicator procedure, see the communication manual.

IMPORTANTDo not turn off the power to the transmitter immediately after performing a zero point adjustment. Powering off within 30 seconds of performing this procedure will return the zero point to its previous setting.

NOTEBefore performing this adjustment, make sure that the external zero adjustment function has NOT been disabled by a parameter setting.

To check the output signal, use a digital multimeter, calibrator, or communicator.

The zero point adjustment can be made with a resolution of 0.01% of the setting range. The degree of zero adjustments varies with the screw turning speed; turnthescrewslowlytomakeafineadjustment,quickly to make a rough adjustment.

When using differential pressure transmitters for level measurement and if you cannot obtain the lower range value from the actual measurement value of 0%, refer to subsection 7.2.2(2).

7.2.2 Adjusting Zero Point for Gauge/AbsolutePressureTransmitters

(1) WhenyoucanobtaintheLowRangeValuefrom the actual measured value of 0% (0 kPa,atmosphericpressure);

For pressure measurement using gauge pressure transmitters, follow the steps below before performing zero point adjustment.

1) Close the tap valve (main valve).2) Loosenthefillplugsothatthepressureapplied

to the transmitter is only the head of the seal liquid.

3) Adjust the zero point at this status.4) Aftertheadjustment,closethefillplugandthen

gradually open the tap valve.

Use a slotted screwdriver to turn the zero-adjustment screw. Turn the screw clockwise to increase the output or counterclockwise to decrease the output. The zero point adjustment can be made with a resolution of 0.01% of the setting range. Since the degree of the zero adjustment varies with the screw turning speed, turn the screw slowlytomakeafineadjustmentandquicklytomake a rough adjustment.

• Close the terminal box cover and the amplifiercover.Screweachcoverintightlyuntil it will not turn further.

• There are two covers that must be locked on the ATEX Flameproof type transmitters. An Allen head bolt (shrouding bolt) under the edge of each cover is used to lock the cover. When the shrouding bolt is driven counterclockwise with an Allen wrench, the bolt rotates upward and locks the cover. (See section8.4.)Afterlockingthecovers,confirmthat they are secure and cannot be opened by hand. Tighten the zero-adjustment cover mounting screw to secure the cover.

• Tighten the zero-adjustment cover mounting screw to secure the cover.

Shut down the transmitter as follows. Steps2)and3)arespecifictothedifferentialpressure transmitters.

1) Turn off the power.2) Close the low pressure stop valve.3) Open the equalizing valve.4) Close the high pressure stop valve.5) Close the high pressure and low pressure tap

valves.

NOTE• Whenever shutting down the transmitter for a longperiod,removeanyprocessfluidthatisin the transmitter pressure-detector section.

• The equalizing valve must be left OPEN.

7.5 Venting or Draining Transmitter Pressure-detector Section

Since this transmitter is designed to be self-draining and self-venting with vertical impulse piping connections, neither draining nor venting willberequirediftheimpulsepipingisconfiguredappropriately for self-draining or self-venting operation.

If condensate (or gas) collects in the transmitter pressure-detector section, the measured pressure maybeinerror.Ifitisnotpossibletoconfigurethepiping for self-draining (or self-venting) operation, you will need to loosen the drain (vent) screw on the transmitter to completely drain (vent) any stagnated liquid (gas.)

However, since draining condensate or bleeding off gas disturbs the pressure measurement, this should not be done when the loop is in operation.

WARNING

Since the accumulated liquid (or gas) may be toxic or otherwise harmful, take appropriate care to avoid contact with the body, or inhalation of vapors.

7.5.1 Draining Condensate1) Gradually open the drain screw or drain plug

and drain the transmitter pressure-detector section.(Seefigure7.5.)

2) When all accumulated liquid is completely removed, close the drain screw or drain plug.

3) Tighten the drain screw to a torque of 10 N·m, and the drain plug to a torque of 34 to 39 N·m.

When you loosen the drain screw or drainplug, the accumulated liquid will be expelledin the direction of the arrow.

7.6 Setting the Range Using the Range-setting Switch

WARNING

The range setting switch must not be used in the hazardous area. When it is necessary to use the switch, operate it in a non-hazardous location.

When pressure is applied to the transmitter, the low- and high-limit values for the measurement range (LRV and URV) can be changed (re-ranged) using the range-setting switch (push-button) located on the optional integral indicator plate and the external zero adjustment screw. This procedure does not require use of the communicator. However, changes in the scale range and engineering unit display settings for the integral indicator require use of the communicator.

Follow the procedure below to change the LRV and URV settings.

[Example]

Rerange LRV to 0 and URV to 3 MPa.

1) Connect the transmitter and apparatus as shown in Figure 8.1 and warm it up for at least fiveminutes.

2) Press the range-setting push-button. The integral indicator then displays “LRV.SET.”

3) Apply a pressure of 0 kPa (atmospheric pressure) to the transmitter. (Note 1)

4) Turn the external zero-adjustment screw in the desired direction. The integral indicator displays the output signal in %. (Note 2)

5) Adjust the output signal to 0% (1 V DC) by rotating the external zero-adjustment screw. Doing so completes the LRV setting.

6) Press the range-setting push-button. The integral indicator then displays “URV.SET.”

7) Apply a pressure of 3 MPa to the transmitter. (Note 1)

8) Turn the external zero-adjustment screw in the desired direction. The integral indicator displays the output signal in %. (Note 2)

9) Adjust the output signal to 100% (5 V DC) by rotating the external zero-adjustment screw. Doing so completes the URV setting.

10) Press the range-setting push-button. The transmitter then switches back to the normal operation mode with the measurement range of 0 to 3 MPa.

Note 1: Wait until the pressure inside the pressure-detector section has stabilized before proceeding to the next step.

Note 2: If the pressure applied to the transmitter exceeds the previous LRV (or URV), the integral indicator may display error number “AL.30” (In this case, the output signal percent and “AL.30” are displayed alternately every two seconds). Although “AL.30” is displayed, you may proceed to the next step.

IMPORTANT• Do not turn off the power to the transmitter

immediately after completion of the change in the LRV and/or URV setting(s). Note that powering off within thirty seconds after setting will cause a return to the previous settings.

• Changing LRV automatically changes URV to the following value.

URV=previous URV+(new LRV–previous LRV)

• If the range-setting push-button and external zero-adjustment screw are not touched during a range-change operation, the transmitter automatically switches back to the normal operation mode.

8. Maintenance8.1 Overview

WARNING

Since the accumulated process fluid may be toxic or otherwise harmful, take appropriate care to avoid contact with the body or inhalation of vapors when draining condensate or venting gas from the transmitter pressure-detector section and even after dismounting the instrument from the process line for maintenance.

Maintenance of the transmitter is easy due to its modular construction. This chapter describes the procedures for calibration, adjustment, and the disassembly and reassembly procedures required for component replacement.

Transmitters are precision instruments. Please carefully and thoroughly read the following sections for information on how to properly handle them while performing maintenance.

IMPORTANT• As a rule, maintenance of this transmitter

should be done in a shop that has all the necessary tools.

• The CPU assembly contains sensitive parts that can be damaged by static electricity. Take precautions such as using a grounded wrist strap when handling electronic parts or touching the board circuit patterns. Also be sure to place the removed CPU assembly into a bag with an antistatic coating.

8.2 CalibrationInstrumentsSelection

Table 8.1 lists the instruments that can be used to calibrate a transmitter. When selecting an instrument, consider the required accuracy level. Exercise care when handling these instruments to ensure they maintain the specified accuracy.

8.3 CalibrationUse the procedure below to check instrument operation and accuracy during periodic maintenance or troubleshooting.

1) Connect the instruments as shown in figure 8.1 and warm up the instruments for at least five minutes (ten minutes for EJX310A.)

IMPORTANT• To adjust the transmitter for highest

accuracy, make adjustments with the power supply voltage and load resistance including leadwire resistances set close to the conditions under which the transmitter is installed.

• If the measurement range 0% point is 0 kPa or shifted in the positive direction (suppressed zero), the reference pressure should be applied as shown in the figure. If the measurement range 0% point is shifted in the negative direction (elevated zero), the reference pressure should be applied using a vacuum pump.

2) Apply reference pressures of 0%, 50%, and 100% of the measurement range to the transmitter. Calculate the errors (differences between digital voltmeter readings and reference pressures) as the pressure is increased from 0% to 100% and is decreased from 100% to 0%, and confirm that the errors are within the required accuracy.
